Lecture :1 Geography: Geography is the study of locational and spatial variation in natural and human phenomena on Earth. Vidal de la Blache Geography is the science of places‚ concerned with the qualities of potentialities of countries. The particuler character of a country is expressed by the totally of its feature‚ the social diversities associated with the diversities of places.Geography mainly divided into two parts. • Physical geography • Human geography Physical

under flooded state‚ which involves the microbial reduction of insoluble Fe3+ insoluble Fe2+ (Beckerand and Asch‚ 2005). The toxicity in plants due to iron is linked to high Fe2+ uptake by roots and its transportation or movement to leaves and via transpiration stream. The Fe2+ surplus causes free radical production that spoils cellular structure irreversibly and damages membranes‚ DNA and proteins‚ reduction of plant photosynthesis and yield (Sinha et al. 1997; Arora et al. 2002; Dorlodot et al. 2005;

Title: You Light Up My Life Purpose: To determine how different environmental conditions affect a plants starch levels. Hypotheses: 1. If the plant that is in absence of CO2 and is kept in a closed environment‚ then it will have a starch level of 1 because the plant is missing CO2‚ which it needs to complete the photosynthesis process. 2. If the plant is in a closed environment‚ then the plant will have a starch level of 3 because it has all the environmental conditions it needs. 3. If the plant

000 mm. Where does all that water come from? Eastern trade winds that blow from the Atlantic Ocean account for about half of the rainfall‚ with the other half due to evapotranspiration - the loss of water from the soil by evaporation and through transpiration from plants - in the Amazon River Basin. If evapotranspiration and its role in maintaining ecological balance are disrupted‚ the climate throughout region - and well beyond - will be significantly

these plants are its specialized leaf cells that excrete salt which are called salt glands while others have salt hairs located in their stem to excrete the salt. Moreover‚ this family of plants are able to adapt through the regulation of the transpiration brought about by the sodium ion that influences the opening and closing of guard cells in order to adjust to the salt present in the environment (Ashour et al.‚ 2002). Thus‚ according to Jouyuban 2012‚ these plant responses and adaptations are

Marketing: A Field of Superb Minds A deep realization about marketing begins its existence when I was browsing on the Internet. An author named Seth Godin captures my oblivious being in view of marketing with an aphorism that goes this way‚ “marketing is a contest for people’s attention”. This line must be too short to consider but it carries a lot of denotations which could be branched out to many ideas. Thinking‚ with respect to my instructor’s introduction of Marketing Management‚ I was near

another strategy to move water in the xylem upwards to the highest points of the plant body. (7) If adequate water is available then the water which lost through the stomata is replaced by the water present in xylem vessel. (8) During day time the transpiration pull becomes the major driving force in the movement of water in the xylem. Q.2 Explain transport of food and other substances in plants. A.2 (1) Carbohydrates are synthesized in the green leaves by the process of photosynthesis. (2) These
